Oxetane, or 1,3-propylene oxide, is an heterocyclic organic compound with the molecular formula C3H6O, having a four-membered ring with three carbon atoms and one oxygen atom.
The term oxetane may also refer more generally to any organic compound containing an oxetane ring.
==Production==
A typical well-known method of preparation is the reaction of potassium hydroxide with 3-chloropropyl acetate at 150 °C:

Yield of oxetane made this way is c. 40%, as the synthesis can lead to a variety of by-products.
Other possible reactions to form oxetane ring is the Paternò–Büchi reaction. The oxetane ring can also be formed through diol cyclization as well as through decarboxylation of a six-membered cyclic carbonate.
